Question

Amit can do a piece of work in 5 days and Sumit in 4 days how long will they take to do the same work together​

Answer 1

Days required by Amit to complete work = 4
1 Day work of Amit = 1 /4
Days required by Sumit to complete work = 6
1 Day work of Sumit = 1 /6
1 Day work of both Amit and Sumit =
( 1 /4 ) + ( 1 /6 )
Time required to complete work =
Total work ÷ 1 Day work
1 ÷ 5 /12
1 × 12 /5
12 /5
2 Whole 2 / 5 Days
